ENGLISH PROJECT – SHRI JAGDISH CHANDRA BOSE:

JAGDISH CHANDRA BOSE:

JAGDISH CHANDRA BOSE Jagdish Chandra Bose was Born on 30/11/1858 at Faridpur , India (now Bangladesh. He received his education first in India, until in 1880 he went to England to study medicine at the University of London. Within a year he moved to Cambridge to take up a scholarship to study Natural Science at Christ's College Cambridge. One of his lecturers at Cambridge was Professor Rayleigh, who clearly had a profound influence on his later work He died on 23/11/1937.

WORKS OF JAGDISH CHANDRA BOSE:

WORKS OF JAGDISH CHANDRA BOSE Just one hundred years ago, J.C. Bose described to the Royal Institution in London his research carried out in Calcutta at millimetre wavelengths. He used waveguides, horn antennas, dielectric lenses, various polarisers and even semiconductors at frequencies as high as 60 GHz; much of his original equipment is still in existence, now at the Bose Institute in Calcutta. Some concepts from his original 1897 papers have been incorporated into a new 1.3mm multi-beam receiver now in use on the NRAO 12 Metre Telescope.

INVENTIONS OF JAGDISH CHANDRA BOSE:

INVENTIONS OF JAGDISH CHANDRA BOSE Nearly 100 years after Guglielmo Marconi's first transatlantic wireless communication, it has come to light that the detector he had used to pick up the signal was invented by Professor Jagadish Chandra Bose. The discovery made by a group of scientists of the US-based IEEE proves what has been a century-old suspicion in the world scientific community: that the honour of being the pioneer in wireless communication should have gone to Bose and not Marconi. Bose's invention of the mercury coherer with a telephone, which Marconi used, was published in the Proceedings of the Royal Society, London, on April 27, 1899, over two years before Marconi's first wireless communication on December 12, 1901, from Newfoundland, now in Canada.

OTHER INVENTIONS OF J.C.BOSE:

OTHER INVENTIONS OF J.C.BOSE Bose's experiments were carried out at the Presidency College in Calcutta, although for demonstrations he developed a compact portable version of the equipment, including transmitter, receiver and various microwave components. Some of his original equipment still exists, now at the Bose Institute in Calcutta. In 1985 the author was permitted by the Bose Institute to examine and photograph some of this original apparatus.

HIS ACHIEVMENTS:

HIS ACHIEVMENTS In 1884 Bose was awarded a B.A. from Cambridge, but also a B.Sc. from London University. Bose then returned to India, taking up a post initially as officiating professor of physics at the Presidency College in Calcutta. Wealth and power never attracted Jagadish chandra Bose. He toiled for science like a saint, selflessly. This great scientist is a great example to all.
